Specification of Letters Patent.

Patented July '7, 1908".

v Application filed October 11, 1907. Serial No. 396,972.

To all whom it may concern.

Be it known that I, WILLIAM WV. VILSON, citizen of the United States, residing at Dallas, county of Dallas, and State of Texas, have invented certain new and useful lmprovements in l/Vashboilers, of which 4the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a wash boiler, and articularly to a construction wherein a circu ation of the water is effected.

The invention has for an object to provide a novel and improved construction of boiler having a heating flue extending therethrough with an inverted funnel surrounding this flue to effect a circulation of the water, and a sleeve interposed between the funnel and flue to comprlse a steam jacket for the rapid production of steam during the heating action of the water in the boiler.

l A further object of the invention is to provide an improved construction of the inverted funnel having channels disposed in connection with auxiliary heaters dependent from the bottom of the boiler so that the heated water rising therefrom is directed by these channels upwardly between the flue and funnel in order to secure the most efiicient circulation thereof.

Other and further objects and advantagesV of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawing z-Fi ure 1 is a vertical section through the boi er; Fig..2 is a plan 5 Fig. 3 vis a horizontal section on the line X-X, Fig. 1, with the funnel removed; Fig. 4 is a detail perspective of the steam jacket.

Like numerals refer to like parts in the several figures of the drawing.

The numeral 1 designates the boiler or receptacle which may be of any desired configuration and is preferably formed with a fiat bottom 2 from which a heating flue or chimney 3 extends upward through the boiler and is adapted to convey the heat and products of combustion from the generating device indicated at 7 upon which the boiler is disposed, as shown in Fig. 1. Surrounding the flue 3 is the sleeve 4 forming a steam jacket which is spaced from the fiue so as to provide a water space at this point, while at its lower end an outwardly directed flange 5 is disposed and may be extended over more or less of the area of the bottom. Both the sleeve and `flange are provided with apertures or perforations, and the flange is supported above the bottom of the boiler by projections 6 so as to leave a small water space within which steam is rapidly generated by the direct heat upon the bottom of the boiler and rises through the perforations of the plate so as to assist in heating the water and giving the circulation thereto.

The bottom of the boiler l is provided with a series of auxiliary heaters 8 which may be of any desired configuration, preferably conical, as shown in Fig. 1, and communicating with the boiler through the contracted openings 9 at their upper ends in alinement with enlarged apertures in flange 5. Coperating with these openings is the inverted funnel 11 provided at its lower end with an inclined flange or bottom plate for the boiler, and having a series of raised channels 12 disposed in alinement with the openings from the auxiliary heaters so as to direct the rising water therefrom through the funnel which is spaced from the flue 43 and also from the sleeve 4. The flange 10 is provided at its periphery with a series of openings 15 to permit the downward passage of water' at the outer portion of the boiler. The funnel is also provided at its top with the downwardly deflected fiange 14 by which the water passing out at this point is deflected back into the boiler and onto the clothes which rest upon the upper surface of the funnel. This funnel is supported above the plate 5 and the bottom of the boiler by lugs or feet 16 upon thefunnel which is spaced from the chimney by braces 17 at the upper portion of the funnel. In order that the funnel may be disposed with the channels 12 in alinement with the openings through the auxiliary heaters an indicating mark 18 is disposed at the side of the boiler, and a cooperating mark 19 upon the funnel so that by alining these marks the channels may be properly positioned.

In the operation of the invention as the water upon the bottom of the boiler becomes heated it passes upward through the funnel and is discharged upon the clothes while the cooler water is drawn downward through the openings in the flange of the funnel and into contact with the bottom of the boiler and also into the auxiliary heaters. These heaters being directly above the most intense heat quickly circulate the heated water upward through the channels into the upper portion of the funnel and the space surrounding the Hue by which the Water is maintained at its high temperature and thus a rapid and positive circulation established at all times. In order to maintain the high temperature of the water and also to subject the clothes to the action of steam, the sleeve or steam jacket is provided and the space between the sleeve and its Hange is suHfciently limited to retard rapid circulation on the heated bottom and Hue and subject a small body of water to intense heat converting the same into steam which rises through the perforations in the jacket or throughthe open upper end thereof thus materially assisting in the circulation of the water upward along the surface of the Hue and causing a quicker boiling action than can otherwise be secured. This steamjacket also acts to radiate the heat by providing an increased heating surface for that purpose. Both the funnel and steam jacket may be readily removed from the boiler for cleansing purposes and a sanitary device thus provided, While the arrangement of channels in the funnel with the indicating marks provides positive means for alining these parts so as to secure in a simple and economically constructed device the most efficient results in rapidly heating and circulating the Water so that in its passage the clothes or goods are cleansed more rapidly than could otherwise be accomplished.

Having described my invention vand set forth its merits, what I claim and desire to secure by Letters Patent is z l. In a wash boiler, a Hue extending therethrough, a sleeve surrounding said Hue and spaced therefrom, an inverted funnel spaced from the Hue and sleeve and above the bottom of the boiler, and a laterally disposed Hange carried by said sleeve beneath said funnel and adjacent to said bottom.

2. In a wash boiler, a Hue extending therethrough, a sleeve surrounding said Hue and spaced therefrom, an inverted funnel spaced from the Hue and sleeve and above the bottom of the boiler, a laterally disposed apertured Hange carried by said sleeve beneath said funnel, auxiliary chambers depending from the bottom of said boiler in alinement with the Hange apertures, 'and conducting channels formed in said funnelin alinement with the discharge from said heaters.

3. In a wash boiler, a Hue extending therethrough, a steam jacket comprising a perforated sleeve surrounding said Hue and a perforated Hange supported above the bottom of the boiler, and a conducting funnel spaced from said sleeve and having a Hange with an imperforate portion disposed above the sleeve Hange.v

4. In a Wash boiler, a Hue extending therethrough, a conducting funnel spaced from said Hue and provided with a lateral Hange at its lower portion having a series of conducting channels inclined from the periphery of the funnel toward the vertical portion thereof.

5. In a wash boiler, a Hue extending therethrough, -a conducting funnel spaced from said Hue and provided with a lateral apertured Hange at its lower portion having a series of conducting channels inclined upward toward thevertical portion thereof, and a series of auxiliary chambers carried by the bottom of said boiler and having openings disposed in alinement with said channe s.

In testimony whereof I aHix my signature in presence of two witnesses.
